23119159 ÷ 161 
We want to figure out the number of times 23119159 can be divided by 161.

On to step 1:
2 divided by 161 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 161

Going ahead to step 2:
161 goes into 23 0 times with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 161

Step 3:
161 goes into 231 1 times with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 161 from 231 and we're left with 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 161

Going ahead to step 4:
When dividing 701 by 161, we get 4 with a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 57 after subtracting 644 from 701.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 161

Advancing to step 5:
161 can be fit into 579 3 times, resulting in a remainder of 96.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtracting 483 from 579 leaves us with 96.
Bring next digit (1) of the dividend behind the 96 and repeat the process: 961 / 161

Let's proceed to step 6:
161 goes into 961 5 times with a remainder of 156.
Record the quotient 5 as the next digit in the result. 
Result so far: 1435.0
If we take 805 away from 961, we end up with 156.
Grab the next digit (5) from the dividend, add it to 156, then carry on: 1565 / 161

Moving on to step 7:
When dividing 1565 by 161, we get 9 with a remainder of 116.
The next digit of our result is 9. 
Result so far: 14359.0
Deduct 1449 from 1565 and we're left with 116.
Include the next digit (9) from the dividend after 116, then repeat: 1169 / 161

On to step 8:
1169 divided by 161 is 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 143597.0
If we take 1127 away from 1169, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
When dividing 420 by 161, we get 2 with a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 143597.2
If we take 322 away from 420, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
161 can be fit into 980 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 143597.26
Subtracting 966 from 980 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
If we divide 140 by 161, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 143597.26
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
1400 divided by 161 is 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 143597.2608
Subtract 1288 from 1400 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
161 can be fit into 1120 6 times, resulting in a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 143597.26086
If we subtract 966 from 1120, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 14:
161 goes into 1540 9 times with a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 143597.260869
Subtract 1449 from 1540 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 15:
If we divide 910 by 161, we get 5 and a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 143597.2608695
The remainder is 105 after subtracting 805 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 16:
The number 161 fits into 1050 6 times, leaving a remainder of 84.
The next digit of our result is 6. 
Result so far: 143597.26086956
Subtracting 966 from 1050 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 143597.26086956, with a leftover of 8.4e-08.
